If you have limited space, like in a small apartment or office, the dimensions can determine if it can fit there. The weight of a router can matter in some situations. But, it is usually not as crucial as other factors. These factors include features and compatibility.


ChipsetRDC R3211-G
Flash4 MB
Power supply12 V / 0.5 A

The RDC R3211-G CPU is key. It, along with factors like RAM and firmware, decides how well the router works. The amount of RAM in a router can affect its performance. It also affects its capacity to handle concurrent operations and traffic. The 4 MB flash memory in the router serves as the storage medium for the router's firmware. Upgrading router firmware has become simple and user-friendly. The Linksys provides the right power supply. It is 12 V / 0.5 A, this matches the router's voltage needs.


LAN ports4 x 10/100 Mbps
WAN ports1 x 10/100 Mbps

Like many modern routers, the WRT54GR supports many network standards too. Most networking equipment, like routers and switches, supports IPv4. Wired connections may bottleneck due to the limits of Fast Ethernet ports.

The 2 x 2 dBi, RP-SMA antennas allow sending and getting many data streams at once. This boosts overall throughput and improves Wi-Fi performance. Many IoT devices, smart home devices, and older Wi-Fi devices mainly use the 2.4 GHz band. The 802.11g operates in the 2.4 GHz frequency band, like 802.11b. But, it offers faster speeds and better performance. Real-world WRT54GR router speeds are lower than its theoretical maximum speed. WEP was the first Wi-Fi security protocol. But it is now seen as weak and easy to hack.


USB portsno

File serverno

The WRT54GR router doesn't have file-server or print-server functionality.
